不同产地、单株美洲黑杨(Populusdeltoides)×青杨(P.cathayana)F1苗期测定研究的结果表明,父、母本对F1苗木生长量有明显的影响,长安种源青杨作父本杂交效果较好,而I-69杨作母本杂交效果较好;就感病程度而言,不同种源青杨间差异较大,而同一种源单株间差异不大。
Populusdeltoides × P.cathayana F1 in different habitats showed that the parents and the female parent had a significant effect on the growth of F1 seedlings, The hybridization effect was better, while the I-69 Yang as female parent hybrid effect is better; in terms of susceptibility, different provenances of different Populus euphratica different, while the same source single difference between.
